Watched the demo, and I can see why you would think he is suspicious from his good aim. Headshot with MG42 is a normal thing in Jaymod as well, it can just be difficult to do as the crosshair is so offset from where the bullets actually hit. But I don't think he is cheating, I only see a good/experienced player who is good at judging his surroundings and has a good aim.

The key to looking for a cheater is not to focus on what might be suspicious, but only to keep a eye on those things and focus more on what is not suspicious. For example, in this demo Mirrori occasionally has enemies passing in front of him and not noticing them as they are fairly far away. Another example is where he sometimes has enemies appear around corners, behind objects and over stairs where he then reacts where a cheater would be able to immediately react or at least anticipate that a player will come around a corner.
